Features of modulated structures in Bi2Sr2Ca1-xYxCu2Oy have been investigated by means of electron microscopy. In addition to two one-dimensional modulated structures with different periods, a new structure modulated along the a and b axes is found in 0.8x1.0. A high-resolution electron micrograph shows that the new structure is characterized by the periodic array of wavy stripes along the b axis.
